BOC Sciences Provides Ultra-sensitive Cyanine Dyes for Biofluorescence Labeling
In order to further promote scientific research in environmental, biomedical and other fields, BOC Sciences has recently updated its product list to provide ultra-sensitive commercial cyanine dyes.
With the rapid development of fluorescence technology, fluorescence detection and fluorescence imaging based on organic fluorescent dyes have been widely used in many research fields such as biological probes and biological tissue staining. Cyanine dyes are fluorescent nucleic acid dyes. Because of its unique conjugated skeleton structure, more modifiable sites, tunability of absorption and emission wavelengths (from visible light to near-infrared region), large molar extinction coefficient and high fluorescence quantum yield, cyanine dyes are widely used in biofluorescence labeling. Cyanine dyes have become the main fluorescent probes used in the analysis and detection of DNA, proteins and nucleic acids.
Cy3 / Cy3.5 / Cy5 / Cy5.5 / Cy7 / Cy7.5
Cy means “cyanine”. Most non-sulfonated cyanine dyes have low water solubility, and organic co-solvents must be added when labeling biomolecules in an aqueous environment. Cyanine dyes are the most commonly used near-infrared fluorescent dyes. Cy7 NHS ester, Cy5.5 amine and Cy3 azide have very low background absorption in the near-infrared region and are the most stable long-wavelength dyes with the highest fluorescence intensity.
Sulfo-Cy3 / Sulfo-Cy3.5 / Sulfo-Cy5 / Sulfo-Cy5.5 / Sulfo-Cy7 / Sulfo-Cy7.5
Sulfonated cyanine dyes have high water solubility and can label biomolecules in pure water environments without the use of organic cosolvents. The sulfo functional group in the dye structure can promote the solubility of the dye molecule in water and reduce the degree of polymerization. The dye molecule can well label the conjugate.
